A remote code execution vulnerability exists within the Network News Transfer Protocol (NNTP) component of the affected operating systems. This vulnerability could potentially affect systems that do not use NNTP. This is because some programs that are listed in the affected software section require that the NNTP component be enabled before you can install them. An attacker could exploit the vulnerability by constructing a malicious request that could potentially allow remote code execution. An attacker who successfully exploited this vulnerability could take complete control of an affected system.
